This invention relates to printing 'and .serving machines tand the principal object Vis to' provide 'a Vlocking .device fofsimple :construction preventing the discharge zof more than the desired'lenrgth'of the'printed stri `from the register. f helockl-isof particurar utilit'yiin conjunction with the'operatingo :self-printing registers by means Vof which t-hepaperstrips are printed as they `are withdrawn fromtheregister'and a feature of this 'device is 4al lock adapted for actuationibyfthe revolution of-.the printing -roll as is hereinafter more"particularly .shown vand described.v A .further object of v the invention is a lockofthenoharacter ldescribedwhioh may :be released from the' exterior vof fthe vmachineV .by l.the operator 'at' theftime it is desired to fwithdraw a printed sheet and that automatically locks as the predetermined length of the' sheet vis `discharged. .These andotherlobjects and the several novel Vfeatures y.ot' the invention are hereinafter more fully described and claimed and shown in the accompanying drawing in whichv y Figure 1 is an-elevation partly in section ofan autographic register and locking -device embodying my invention.

ofjFebruary 12, 1918 zin which a third roll ofrblank'paper :is provided. The two rolls shown here, however, serve tolillustrate the Ihefupper 'cover-'9 of register has an opening @exposing lthe upper. strips vto view for.. the'purpose of writing thereon vand the upper strip infthefarrangement showniisgwithdrawnkas indicated yat 10, -while the lower istrip istaken'ful on a rewind roll 11 ait the forward Aend zo' the-machine. The paper .strips are drawn from the rolls byimeans of the roll .12 and the lower roll indicated at 13 which has'a handle 214 and the 'upper .roll engages therewith undersuiicientten'- sionl to withdraw the paper from the `rolls and rotate the printing roller or the print- Y'ing 'roller lfmayjbe "directly, driven 'by the operatingrollvif desired. n

VThe Vprinting irollhere shown is Ato be considered as one `in whichithe type or printing :surfaceV isj'of such length to require. one frevolution ofgth'e roll .to impress 'the :same .uponthe strips. The printing surface may, however, be formed of two-'or moredupli-V catefportions :thereon so that upon 'revolution offtheprintingroll two or more imprese sions'are made upon thel aper strips andthe function ofthe locking evice is to stop the unwindingof the 4strips from the roll'and discharge thereof from the machine between each-separate impression onxthe strip. For this purpose the printing roll shaft is provided withacam member 15 having a notch lthereinand a lever 17 is pivotally supportedon a shaft `18;,having an end 19 adapted to engage thesaid notch 16 of the cam. Ashere shown there is but@ one notch 16provided, but lin case the printing surface is duplicateor triplicate in character the cam should be `provided with an equal number of notchesas will be readily understood.`

The operating :roll 13 is provided at one end with/a toothed fwheel 20 and the forward end of the lever 17 is'jprovided with a tooth 2l adapted to enga efbetween fthe teeth of the wheel 520.; The orward end 0f the lever depressing the inthe construction here shownjisprovided` with an upward extending arm `22 and a pin 23 is providedin the upperfpart 241.gif the case covering the tension roller 12, the

order to rotate thesame the ypin 23 is de-v pressed as indicated inFig. .3, withdrawing `the tooth 21 from the gear wheel and allowying the rolls'12 and 13 to be rotated draw paper from the paper rolls. This .pin vshould be Vheld depressed upon beginning offrotation of roll 13 by the handle 14 V'for to with a slight period ltoallow the high part ofthe cam member 15 to engagebeneathfthe end 19-of thelockinglever which is held in the -rolls 13 and A12 ma'yf-then` be turned withdrawing the-,paper until'l the notch; 16 kof the camfagain comes'beneath-the' end'19 of the'lever, which by action ofthe spring 25,
